UPDATE2: Stratified couldn't get rid of my rev hang and Dizzy is far smoother and now have dyno's
So first off, this is to discuss my findings, pros and cons and encourage thoughts and recommendations including what to ask for in a revision on one or both. I have an e30 tune only with Dizzy, so for discussion purposes, 93 tunes, in initial flash form will be discussed here, I'll be running my Dizzy e30 as much as possible regardless because of COURSE!
Options: None of my tunes has pops and crackles, have linear throttle option on Stratified, same 5000 RPM FFS on both. Launch control is set for 3000 for hard and soft on Stratified, Dizzy I asked for 2750 but that is set only as soft limit, hard limit is set much higher, if I want to launch/drag race I'd have to manually adjust the Dizzy hard limit down first. I also have 91 octane with my Stratified as it was only a $15 option since I do drive down to Cali with worse gas sometimes.
Mods: Drop in air filter with shroud cut out for snorkel, muffler to glasspack swap, symposer delete, short shift plate, Torque Solutions RMM, passenger side mount insert/bolt and step colder plugs. So you could say a stage 1+, intercooler will come next year. Driver side insert and TB Performance traction bar is on hand and waiting to go in now, still trying to find the tools, time and possibly help I need.
NEW: Dyno's below, with Dizzy tine and upgrades, torque peaks at a more manageable 3500 RPM.: Added Upgraded crossover, turbo inlet and a TurboSmart VR2 EM plum back electronic DV. Works amazing, just wish it was a touch louder, stock is even louder with a little pssst with a drop in filter.
Idle speed: With my Stratified at 850 and Dizzy at 900, I say 850 is perfect with upgraded mounts.
With Stratified, for some reason I still get big rev hang and with Dizzy I only get a little even with option for it on. Stratified was not able to remove it. It is SUPER annoying with the Stratified, takes away a lot of the fun of it, but I understand this is NOT typical.
Next is off the line behavior, under medium and up acceleration, Dizzy is MUCH smoother while Stratified can hit hard with torque quite suddenly after the one second of turbo lag, after each shift, not sure how I like that. It can be fun for around town stop light to stop light, but Dizzy is much better for commuting in traffic. Again, rev hang sucks on the Stratified, makes for it a little more difficult to drive smoothly between the rev hang and then the sudden torque hit.
With Stratified, I have their version of traction control on by default at their recommended Optimal setting and Dizzy has Cobb TC set at 3 and enabled by default, both feel very similar at the 93 octane level, wheel spin and torque steer are very similarly minimal.
Now for multi-gear WOT pulls, as far as boost, I am seeing Stratified hit a peak boost of 26.5 and the Dizzy hit up to 25.0. Both pull through the powerband at a couple of PSI less than each ones peak. Symposer delete has helped hold boost a bit better through the 3000-5000 full boost range. Max safe boost on a stock turbo is a debatable topic so I can say that I LOVE the engagement, quickness, immediate pull and sounds of the Stratified tune through the gears, but Dizzy is smooth and strong but not quite as aggressive and engaging but in a good way. Dyno results later confirm Dizzy is just as powerful with even a little more torque, I'm sticking with Dizzy as my main tune now, period
Both get great freeway mileage and feel pretty similar when you are in 6th and above 2500 RPM so you can floor it safely without much LSPI risk, but surprisingly, despite the less aggressive boost and timing, somehow Dizzy is more responsive when you want some quick part throttle acceleration at lower RPM's without shifting down, again Dizzy wins here too.
Also, despite the more aggressive boost and timing, for some reason Stratified doesn't heat soak the stock IC quite as bad, maybe because it has a more aggressive engine fan profile, or maybe runs slightly richer?
Having vDyno's to compare although they both have similar power, it seems Stratified is racey and twitchy while Dizzy is the more refined and smoother "gentleman's tune", I kind of wish I could mix and match the qualities of both to get the tune I want: The smoothness off the line without rev hang, like it is on Dizzy, but with the sheer responsive engagement and sounds of the Stratified during multi-gears pulls, but at the exact perfect boost level that won't cause damage as well
To summarize:
Dizzy:
Pro's - SMOOTH, both off the line and how boost engages, better cruising low RPM throttle response, feels safe with it's less aggressive boost and timing but still very strong. Includes a datalog review for safety at base price, can have Cobb traction control on or off by default and at what setting you want, I like mine set for 3. Simple tune options easy to configure, no nickel and dime pricing for each option with good flat rate price. Regular awesome sales for every little holiday that include both a pump and e30 tune for only $75 total. Simple 2 main stages available to order but still get to list all your mods and even your elevation. Faster email response than Stratified.
Con's - For some reason runs a bit hotter and heat soaks the IC quicker than Stratified. Definitely feels slightly too conservative in initial flash form, have to pay for custom tuning to request more boost and timing through datalogging. Has separate hard limit set way too high for launch control, only sets soft limit at what RPM you request. I'm sure he will set them both more accurately if asked on his tuning form, he only recently added some features with his V2. I forgot I ordered rev hang left on, I think, but not bad feeling at all, less invasive than the my Stratified tune, which could not be fixed. Not quite as many tune options, no multiple pump octane option, either 91 or 93 only. Tune email does not have super detailed info.
Verdict: Best safe and smooth flash tune for someone who just wants to flash once and be done with it; knowing they are running safe but strong with good refinement for daily driving and aren't the type to even monitor their AP. Don't plan on pull after pull after pull on hot days or racing without an IC upgrade even on his stage 1. But also, the e30 tune avaiable is insanely fun and smooth to max out your stock turbo.
Stratified:
Pro's: Dat sweet feel and sound of full gear pulls with aggressive timing advance that helps the car pulls out quickly for a more racey feel. Runs surprisingly cooler that Dizzy even with more boost and timing in initial flash form, partly due to more aggressive cooling fan speed ramping. Lots of multiple octane features available but now base price same as Dizzy. Tune email itself is loaded with tons of good info, has amazing library of tech articles for the public that help you learn a lot.
Con's: Mine has horrible rev hang and. Not as smooth as Dizzy with boost hitting a little suddenly in part throttle but not horribly so and with some more miles on it now has seemed to smooth out. Possibly slightly excessive boost on their pump tune, only about 0.5 psi less than Dizzy e30 in flash form, I even had that lowered but still peters out up top. Not as responsive to moderate throttle input as Dizzy at low RPM while cruising in gear. Choices and options when ordering can be a little overwhelming, prices have gone up, their traction control is not worth the extra $15 compared to the options of Cobb you already have, that is the same exact style anyway.
Verdict: Not worth the cost over Cobb OTS for free honestly, don't let Cobb's completely bullshit requirements steer you away from using their Stage 2 mostly stock and just an IC upgrade is actually strongly recommended for stage 3 really. Intake upgrades do help a little, but exhaust is 100% for sound and not a truly needed bolt on at all.
Both:
Offer crackles and pops at both low and high options although Dizzy does also offer which exact RPM you want them to engage, not my thing personally, I like the little bit I get naturally with my glasspack muffler.
Dizzy=blue, Stratified= Red
Dizzy e30 at 35 degrees, 320ft/lb of torque, fully corrected still 300ft/lbs!
